介绍了东莞篮球中心主体育馆大跨度钢结构屋盖和三向网格曲面索网幕墙结构的设计特点。重点阐述了索网幕墙计算模型的建立、屋盖钢结构模型和索网幕墙简化模型的计算分析以及屋盖钢结构与索网幕墙结构组合的完整模型的计算分析,研究了屋盖钢结构和索网幕墙结构之间的相互影响。在完整模型中,屋顶环梁的变形减小,索网的变形增大,索网的拉力减小。设计经验可为复杂大跨钢结构屋盖和索网幕墙结构提供参考。
The design features of large-span steel structure roof and three-dimensional gridded cable net curtain wall structure of Dongguan Gymnasium were introduced. The establishment of calculation model of cable net curtain wall, the calculation and analysis of roof steel structure model and simplified model of cable net curtain wall and the calculation and analysis of the complete model of roof steel structure and cable net curtain wall structure are mainly discussed. Cable network structure between the interaction. In the complete model, the deformation of the roof ring beam decreases, the deformation of the cable network increases, and the tension of the cable network decreases. Design experience can provide reference for complex long-span steel structure roof and cable net curtain wall structure.
